Summary:

Data generated by cloud deployments will grow faster than data center traffic in general over the next few years, according to new Cisco research.

Traffic Jam

The sheer amount of data affiliated with cloud applications will be the fastest-growing part of data center traffic over the next few years, according to new Cisco Systems research. Given the amount of noise around cloud and the increasing move toward the everything’s-connected world of internet of things this growth should come as no surprise.

The cloud-generated portion of data center traffic will soar to 5.3 zettabytes in 2017, up from 1.2 zettabytes in 2012, a 35 percent compound annual growth rate (CAGR), according to the Cisco Global Cloud Index (2012 – 2017). That outstrips the growth rate of global data center traffic generally, which will grow at a 25 percent CAGR for the same period.

The third-annual index aims to forecast the growth of global data center and cloud-based IP traffic, Cisco said.

If you look at the chart below, the sheer volume of cloud data neared parity with traditional data in 2012. But scan across to the projection for 2017. Yowza.

Some other takeaways:

  • Annual global data center IP traffic will hit a whopping 7.7 zettabytes by the end of 2017 and global data center IP traffic will reach 644 exabytes per month (up from 214 exabytes per month in 2012).
  • About 17 percent of all data center traffic will come from end users accessing cloud services —  video streaming, web surfing, online collaboration etc. and the move towards the Internet of things — a key topic at this week’s Mobilize conference — will fuel this hot-growing segment.
  • 7 percent of data center traffic will happen between data centers — for such jobs as data replication and software updates
  • 76 percent of that traffic will happen within a given data center generated by storage, production and development tasks in virtualized environments.
  • The Middle East and Africa will show the highest regional growth (57 percent CAGR); followed by Asia Pacific (43 percent CAGR) and Eastern Europe (36 percent CAGR)
  1. with facebook, twitter, etc etc, how much more can we take!
